I have access to see properties on market with assumable mortgages for FHA. 

Quote from @Quan Pham: I'll give you the easy answer: sell.If you were fired up about owning an investment, I would recommend keeping the house as a rental.

Also, to your point, it's easy to realize returns off 35k invested - especially when the principle payment year 1 alone is around 15k.

I’m definitely working hard to create a solid foundation for both my family and my investments, and it’s encouraging to connect with like-minded people who are exploring real estate as well.You’re absolutely right about Section 8 housing, the stability of cash flow is definitely a big draw for me, especially with the U.S. market being more accessible in terms of affordability compared to Canada.

There's no blanket number that will make the math very easy.

Also look at those Vrbo and Airbnb calendars and see how full they are and what nightly rates they are getting.Should be easy from here to see if a new property would pencil in or not. 

A handy search bar in the upper right makes it easy to find previous discussions, blogs, podcasts, and other resources.

Real estate is easy to get into, but hard to earn a living. 87% of all agents quit within two years because they don't make enough money.

Small is easy to maintain as long as renovations were done correctly.

So, if you have 10 units and you are going to pay $1,500 a month and you are working on an active income job, too, this is an easy switch due to the labor mentally and physically (even if it is just phone calls) to get these rentals running as a well-oiled machine.
